    摘要: Methods are disclosed, such as those involving increasing the density of isolated features in an integrated circuit. Also disclosed are structures associated with the methods. In one or more embodiments, contacts are formed on pitch with other structures, such as conductive interconnects. The interconnects may be formed by pitch multiplication. To form the contacts, in some embodiments, a pattern corresponding to some of the contacts is formed in a selectively definable material such as photoresist. The features in the selectively definable material are trimmed to desired dimensions. Spacer material is blanket deposited over the features in the selectively definable material and the deposited material is then etched to leave spacers on sides of the features. The selectively definable material is removed to leave a mask defined by the spacer material. The pattern defined by the spacer material may be transferred to a substrate, to form on pitch contacts. In some embodiments, the on pitch contacts may be used to electrically contact conductive interconnects in the substrate.

    摘要: Embodiments of the disclosure include a shallow trench isolation structure having a dielectric material with energetic species implanted to a predetermined depth of the dielectric material. Embodiments further include methods of fabricating the trench structures with the implant of energetic species to the predetermined depth. In various embodiments the implant of energetic species is used to densify the dielectric material to provide a uniform wet etch rate across the surface of the dielectric material. Embodiments also include memory devices, integrated circuits, and electronic systems that include shallow trench isolation structures having the dielectric material with the high flux of energetic species implanted to the predetermined depth of the dielectric material.

    摘要: Some embodiments include methods of forming patterns of openings. The methods may include forming spaced features over a substrate. The features may have tops and may have sidewalls extending downwardly from the tops. A first material may be formed along the tops and sidewalls of the features. The first material may be formed by spin-casting a conformal layer of the first material across the features, or by selective deposition along the features relative to the substrate. After the first material is formed, fill material may be provided between the features while leaving regions of the first material exposed. The exposed regions of the first material may then be selectively removed relative to both the fill material and the features to create the pattern of openings.
